From: Chengwen Feng fengchengwen@huawei.com
The 802.11 physical PMA sub-layer defines three media: copper, fiber and backplane. For PMD, the backplane is similar to the fiber, the main differences are that backplane doesn't have optical module.
Because the interface of firmware fiber is also applicable to the backplane, this patch supports the backplane only through simple extension.
